Electro-Harmonix Micro Q-Tron Envelope Filter Pedal. Smooth envelope filter with a funky wah-wah tone! The EHX Micro Q-Tron is a smooth envelope filter with a funky wah-wah tone. The filter is controlled by its internal envelope follower, analyzing the volume of your notes and the dynamics of your playing to directly sweep the filter’s center or cutoff frequency. A stronger attack or louder note will produce a wider frequency sweep while softer playing produces more subtle effects. Use the Q control to make the effect more dramatic. Product Highlights: True bypass. Drive control sets sensitivity and filter sweep range. Selectable low pass, band pass or high pass filters. Q control sets the filter’s bandwidth from smooth to funky. Tough and compact die-cast chassis. 9V battery included. Product Features: (LP BP HP): Determines what frequency range the filter will pass. Q Control: Determines the peak bandwidth of the filter. Drive Control: This is the filter sweep sensitivity control. Output Jack: Connect your amplifier to the AMP jack. Input Jack: Connect your instrument to the INPUT jack. Footswitch: Toggles between effect and bypass modes. Product Specifications: Circuit: Analog. Bypass: True Bypass. Audio: Mono. Power Supply: 9V battery included (optional 9.6VDC-200mA power adapter not included). Dimensions (in): 4.75 x 4 x 2.25. Current Draw: 15mA. Year Released: 2006. UPC: 68327405002.

Electro-Harmonix Hot Wax Dual Overdrive. The next evolution in inspired overdrives! Awesome on guitar and bass, the EHX Hot Wax fuses our Hot Tubes and Crayon pedals into one powerful dual-overdrive. Each section can be engaged independently, for two very different overdrive flavors, or together to create a massive overdriven sound. The Hot Wax includes a two-knob EQ (BASS and TREBLE) for extensive tonal control, and a BLEND control to mix between your dry and distorted sound. These three controls are active with either or both distortion sections engaged, and bypassed when both overdrive sections are turned off. Product Highlights: Combines the Crayon full range overdrive and the Hot Tubes, a reissue of the classic 1970s CMOS overdrive. Use the Crayon or Hot Tubes alone or stack them with the Crayon driving the Hot Tubes. Sounds great on guitar and bass. Blend control lets you blend in your dry signal which is especially useful on bass guitar. Master EQ section features Bass and Treble for increased tonal control and flexibility. Quiet pop-free foot switching. Power adapter included. Product Features: Vol Knob (Hot Tubes): Sets the master output level. Drive Knob (Hot Tubes): Sets the intensity. Vol Knob (Crayon): If only the Crayon is active, the VOL knob sets the master output level. If both sections are active, the VOL knob sets the level between the Crayon's drive section and the Hot Tubes' drive section. Drive Knob (Crayon): Sets the intensity. Bass Equalization Knob: Boosts or cuts low frequencies. Treble Equalization Knob: Boosts or cuts high frequencies. Blend Knob: Mixes the dry and distorted signal. Output Jack: 1/4" audio output. Input Jack: 1/4" audio input. Hot Tubes Footswitch and LED: Left LED (red) illuminates when Hot Tubes is engaged. Crayon Footswitch and LED: Right LED (green) illuminates when Crayon is engaged. Product Specifications: Circuit: Analog. Bypass: Buffered Bypass. Audio: Mono. Power Supply: 9.6VDC-200mA power adapter included. Dimensions (in): 4.75 x 4.13 x 2.25. Current Draw: 75mA.
